[#1268] Attempt to fix accented characters in gmail headers

Yet another attempt to force gmail to display email headers when they contain
non-ascii.  This time we split the text on word boundaries and separately add
each word to the header.  This yields a header where some parts may be iso-8859-1
encoded and some may be plain ascii.  This should at least let gmail's brain-dead
parsing succeed in finding a return address....
